PFAS in Voglans's tap water: 15 ng/L, 30x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
30× above our health benchmark
0.5 ng/L is our benchmark, not an official limit. Same EFSA method as Sweden, Denmark and the Netherlands, but stricter. It's a yearly average, compared here with the latest check.
More about this result
The US also limits PFOA and PFOS to 4 ng/L each, per substance.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Voglans, the 4 most closely watched PFAS (PFAS-4) add up to 15 ng/L (0.015 µg/L) at the latest PFAS check on 30 July 2026. That's 30 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 42 ng/L (0.042 µg/L), below the EU legal limit (100 ng/L). 9 checks since 24 September 2025: PFAS-4 up to 33 ng/L, sometimes below the detection limit, averaging at least 13.71 ng/L over 12 months (non-detects as 0). Falling on the main network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Voglans safe to drink?
Yes. At the check on 30 July 2026, the tap water in Voglans was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”
How high are PFAS levels in Voglans's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 42 ng/L. The EU limit is 100 ng/L, so this water is at 42 % of the limit. (below the EU limit)
Does the water in Voglans also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 15 ng/L. That is 3.8 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).
Are PFAS levels rising in Voglans's tap water?
No, they are falling. On the main network, the PFAS-4 sum went from 33 ng/L (22 October 2025) to 15 ng/L (30 July 2026) across 6 quantified checks. These history statistics use laboratory-published sums only.
How hard is the water in Voglans?
The water hardness in Voglans is 32.6 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 21 September 2026.
